Tisiwi Ventures

Tisiwi Ventures is an angel and early-stage venture capital firm based in Hangzhou, Zhejiang province, China, founded in 2010 by Xiaowei Pang. It focuses on early-stage Chinese internet and technology startups and was one of the earliest investors in China to adopt the Y Combinator model, aiming to become the country's leading angel investing platform and to provide professional, hands-on assistance to Chinese internet entrepreneurs, and it is willing to lead. The firm operates dedicated investment programmes by stage: angel-round cheques of roughly 1 to 5 million RMB for projects with early users and validated product value, and Pre-A cheques of roughly 5 to 10 million RMB for teams with strong growth data not yet ready for a Series A, with overall ticket sizes spanning approximately 1 to 30 million RMB, about USD 140,000 to 4.2 million. Tisiwi has raised four funds, through Tisiwi Fund 4, and has made on the order of 111 investments with three recorded exits. Its portfolio spans a broad set of sectors including robotics, transportation, consumer electronics, education, media, health, energy and biotechnology, with a recent emphasis on AI and robotics. Representative portfolio companies include Westlake Robotics, its latest investment in a January 2025 seed round, West Lake Xinchen in AI psychological-service technology, Zhuoyin Intelligence in synthetic data for AI training, Nuka Smart and Join AI. By adopting an accelerator-style model early and backing founders from the angel through pre-Series A stages, Tisiwi Ventures has built one of China's more prolific early-stage investing platforms.
